Plot Ko Dok-Mi (Park Shin-Hye) lives peacefully in apartment #402 at Ocean Village. She rarely leaves her apartment. Since last fall, Ko Dok-Mi has peeped out her apartment at her neighbor Tae-Joon (Kim Jung-San), who lives across from her. Peeping at Tae-Joon has become part of Ko Dok-Mi’s daily routine. Her comfortable and peaceful life is shattered, when a group of handsome neighbors appear at her door.

Video game designer Enrique Keum (Yoon Si-Yoon) just came to Korea from Spain. He lives with Tae-Joon. Oh Jin-Rok (Kim Ji-Hoon) lives in apartment #401 with his assistant Dong-Hoon (Ko Gyung-Pyo). Oh Jin-Rok is a web comic writer and begins writing his new comic by observing Ko Dok-Mi. There’s also Watanabe (Kouki Mizuta), who moved next to Ko Dok-Mi.

The men has gathered, because Enrique Keum caught Ko Dok-Mi peeping at Tae-Joon.
